DY-HL30F Industrial Grade Voice Player Module MP3 WAV 9 Channel Trigger Playback Board 9-24V DC 10-30W Speaker 4-8Ω Low High Level Trigger

DY‑HL30F Industrial Grade Voice Playback Module

📌 Product Overview The DY‑HL30F is a 9‑channel one‑to‑one trigger audio playback module, supporting MP3 and WAV audio decoding. It provides two trigger versions: high‑level trigger and low‑level trigger. The module adopts 9‑24VDC wide‑voltage power supply design, built‑in 30W Class‑D power amplifier, which can directly drive 4‑8Ω, 10‑30W speakers. It is equipped with 64Mbit (8MB) on‑board flash memory. Users can connect it to a computer via USB interface to replace audio files freely. It supports volume adjustment via potentiometer, external warning light access and multiple configurable trigger modes, widely used in industrial voice prompt, equipment alarm, automated guide system and other scenarios. ✨ Core Features

• Wide voltage power supply: 9‑24VDC input
• 9 independent trigger interfaces, one‑to‑one control for 9 audio tracks
• Two optional versions: high‑level trigger and low‑level trigger
• Decode MP3 / WAV audio format, maximum sampling rate up to 48KHz
• Built‑in 64Mbit (8MB) flash storage, update audio files through USB connection
• Integrated 30W Class‑D amplifier, directly drive 4‑8Ω 10‑30W loudspeakers
• Reserved interface for external warning light (warning light voltage shall match power supply voltage)
• DIP switch to configure multiple trigger playback modes
• Potentiometer for manual volume adjustment
• High‑level version supports optical isolation for stable industrial use
